Acorns takes an $11.63 purchase, rounds it to $12, and invests the $0.37 difference without being asked. It also charges a monthly subscription, which on a $500 balance works out to somewhere between 7.2% and 28.8% of the account over a year, depending on which plan you're on. The size of the balance settles which of those two facts dominates.
Acorns launched in August 2014 and reports more than 10 million users. It's a micro-investing app and robo-advisor built for people with little or no investing experience: it collects spare change from linked cards, puts it into exchange-traded funds, and rebalances the mix for you. An ETF is just a bundle of stocks or bonds traded as a single item, so you're not picking individual companies.
What Each of the Three Membership Tiers Includes
Everything at Acorns runs through a subscription. There are three: Bronze, Silver, and Gold.
| Feature | Bronze | Silver | Gold |
|---|---|---|---|
| Monthly fee | $3 | $6 | $12 |
| IRA match | None | 1% | 3% |
| Individual stocks | N/A | N/A | Around 100 stocks and ETFs |
| Checking account APY | None | 2.18% (as of 12/11/25) | 2.18% (as of 12/11/25) |
| Emergency fund (savings) APY | N/A | 3.35% (as of 12/11/25) | 3.35% (as of 12/11/25) |
| Bonus investment match | None | 25% | 50% |
| Life insurance | N/A | N/A | $10,000 coverage |
| Kids' investing tools | None | None | Acorns Early Invest custodial account with 1% match |
| Will and trust setup | N/A | N/A | Included |
There's no free tier and no way to skip the monthly charge, which is where the math starts.
A Flat Monthly Fee Is Expensive on a Small Balance
Most robo-advisors charge a percentage of assets, so the dollar cost scales with the account. Acorns charges the same dollar amount whether you hold $500 or far more, which flips the math for small balances.
On a $500 account, the annual subscription comes to between 7.2% and 28.8% of the portfolio depending on the plan.
For comparison, Betterment charges a 0.25% annual advisory fee, and SoQi (SoFi Active Invest) doesn't charge an advisory fee at all.
The flip side is that a flat fee shrinks as a share of assets as the balance grows. The same $3 a month that's a heavy drag on a starter balance becomes a smaller slice of a larger one. The fee is fixed; the balance isn't.
Round-Ups Only Move Money Once Spare Change Reaches $5
Round-Ups are the feature Acorns is known for. You link credit and debit cards, and each purchase gets rounded up to the next dollar. Your card is charged the round number, and the difference heads to your Acorns Invest account once pending Round-Ups reach or exceed $5 from an external account.
Two settings change how aggressive this gets. Spend exactly $10 and the whole-dollar Round-Up invests $1. A multiplier scales the rest: a $25.80 purchase creates a $0.20 Round-Up, which a 2x, 3x, or 10x setting turns into $0.40, $0.60, or $2.00.
There's a practical wrinkle here. Because the money comes from card activity, the contribution rate follows spending habits.
Someone who pays for most things by card generates a steady trickle; someone who mostly uses cash or pays a handful of large fixed bills each month generates very little, and the subscription fee arrives either way.
Recurring Investments Start at $5
Round-Ups aren't the only way in. You can schedule recurring transfers from a linked bank account daily, weekly, or monthly, starting at $5, and add one-off amounts on top whenever you want. For people whose main goal is building the habit, this is the more predictable lever of the two.
You Choose a Risk Level, Not Individual Holdings
Customization is thin, and that's deliberate. On Bronze and Silver, the risk profile is the only portfolio setting you control:
- Conservative: 100% bonds
- Moderately conservative: 60% bonds, 40% stocks
- Moderate: 40% bonds, 60% stocks
- Moderately aggressive: 20% bonds, 80% stocks
- Aggressive: 100% stocks
Acorns picks the ETFs behind each profile; one Bronze account got six ETFs after the risk level was edited. Gold members get access to around 100 stocks and ETFs for building their own mix.
As markets move, Acorns rebalances back toward your target allocation using an algorithm rather than a human advisor. Investing carries risk, including loss of principal, and rebalancing manages allocation, not outcomes.
The IRA Match Is the Clearest Case for Paying More
Acorns Later applies the same questionnaire-driven approach to retirement accounts, using answers about age, employment, and income to recommend a stock and bond mix. Roth, traditional, and SEP IRAs are all available, and you can fund them with automatic paycheck deposits or recurring transfers.
The match is what makes the higher tiers interesting. Silver adds 1%; Gold adds 3%. Contribute the $7,000 annual maximum on Gold and the match comes to $210, against $144 in annual subscription fees, leaving $66 in the account's favor.
For context, Robinhood offers a 3% IRA match at $5 a month.
Mighty Oak Checking Pays 2.18%, but Bronze Members Can't Get It
Bronze includes a basic checking account with no standout features. Silver and Gold unlock Mighty Oak Checking, which pays 2.18% APY (as of 12/11/25) on the regular balance and 3.35% APY (as of 12/11/25) on the emergency fund savings bucket. It comes with a Mighty Oak debit card, and Lincoln Savings Bank or nbkc bank issues it, with FDIC insurance up to $250,000.
Those rates run above a lot of online banks. SoFi, for instance, offers up to 3.10% APY on savings with direct deposit and 0.50% APY on checking, and charges no monthly fees. So the Acorns banking rates are competitive, but you're paying a subscription to reach them, and rates on any of these accounts can change.
Bonus Investments, Kids' Accounts, and Estate Documents Fill Out the Higher Tiers
Acorns Earn pays bonus investments when you shop through more than 10,000 partner offers, Walmart, Apple, Chewy, and Nike among them. It behaves like a shopping-portal cash back program: browse offers in the app, tap through, complete the purchase, and the reward shows up in your investment account.
A Chrome and Safari browser extension makes it less fiddly. Silver adds a 25% bonus investment match and Gold a 50% match.
Gold also bundles in items you wouldn't expect from a micro-investing app: Acorns Early Invest custodial accounts with a 1% match, $10,000 of life insurance coverage, and will and trust setup. Whether those change the value of the $12 depends entirely on whether you'd otherwise pay for them.
No Trading, and No Tax-Loss Harvesting
Acorns doesn't offer trading. If you want to buy a specific stock at a specific moment, this isn't the platform, even on Gold. It also isn't among the robo-advisors that do tax-loss harvesting; Wealthfront is one that does, and it also offers dividend reinvestment and access to cryptocurrency.
How Acorns Compares With Stash and Robinhood
| Acorns | Stash | Robinhood | |
|---|---|---|---|
| Monthly cost | $3, $6, or $12 | $12 | No monthly fee on the basic account |
| Selection | Preset ETF portfolios; around 100 stocks and ETFs on Gold | Over 4,000 stocks and ETFs | More than 5,000 stocks |
| Automatic spare change | Round-Ups | No Round-Up equivalent; auto-invest set up manually | N/A |
Stash is the closest comparison and the more hands-on of the two, with a far wider selection and a Stock-Back Card that pays up to 1% in stock from publicly traded companies where you shop.
An Amazon purchase earns Amazon stock, and non-partner purchases still add a percentage to your investing account.
Robinhood is built for people who want to trade. It has no fee to open or maintain an account and no inactivity fee, fractional shares from as little as $1, commission-free options trading, and crypto buying and selling. It does charge $100 to transfer your money out to another broker.
The difference shows up in selection. Stash lists over 4,000 stocks and ETFs and Robinhood more than 5,000, both of which have to be chosen from; Acorns hands over a preset portfolio unless you're paying for Gold.
What Shows Up at Tax Time
You'll owe taxes on more than $10 in dividends or more than $600 in referral and other bonus offers, and potentially on gains if you sell investments or withdraw a lump sum from Acorns Invest.
A tax professional can size that up for your situation. Acorns also asks for your Social Security number. The Patriot Act requires financial institutions to verify identity, and Acorns uses the number to issue year-end tax forms.
Who Acorns Fits and Who It Doesn't
Acorns is a competent on-ramp with a fee structure that punishes small accounts. It suits someone brand new to investing who wants contributions on autopilot, or a saver who'll actually use the higher-tier IRA match and the Mighty Oak rates.
It fits poorly for anyone planning to keep a few hundred dollars in the account, and it isn't built for a seasoned investor with specific holdings in mind or an interest in active trading.
Gold's $12 a month comes to $144 a year, spread across the 3% IRA match, the banking APYs, the custodial account with its 1% match, the $10,000 of life insurance, and the will and trust setup.
A maxed-out $7,000 IRA contribution covers that $144 on its own and returns $210. Leave the IRA empty and the same $144 is buying whichever of the remaining features actually get used.
